Tech Radar

Ask why»

When I was working at Futurice eight years ago, we had these stickers with the words “Ask why” on it. It should be a reminder to ask ourselves, customers and end users the right questions.

Why is there a technology radar?»

One of the first technology radars was probably the one from the company ThoughtWorks, the idea probably dates back to 2008.

They say about themselves:

We are a leading global technology consultancy that integrates strategy, design and software engineering to enable enterprises and technology disruptors across the globe to thrive as modern digital businesses.

So they see the radar not only for themselves, but almost as a recommendation for the entire industry. Think big! ;) They have a Technology Advisory Board of around twenty people, who contemplate about this. They have divided the radar view into four other quadrants, which usually are Languages & Frameworks, Platforms, Tools and Technology. Because of their attitude, they describe the rings/orbits like this:

One company that jumped on the band wagon was Zalando with slightly other quadrants as well as some tempered description of the orbits. They state about the radar that it should

support Engineering teams at Zalando to pick the best technologies for new projects; it provides a platform to share knowledge and experience in technologies, to reflect on technology decisions and continuously evolve our technology landscape.

In other words, while putting time and effort into doing this visualization, it could probably be helpful for consolidation and strategy decision if done right and recurring. Managers like dashboards, so they might love it! ;)

Why would I do another radar visualization?»

Nowadays I work at Valiton which has its own Technology radar since not so long ago. It was implemented by a colleague of mine with React almost starting from scratch.

Because I am doing stuff with Svelte in my spare time and thought about some meaningful idea, I thought this would have a nice scope to do as a side project. I also think, it might be even easier done with Svelte and SVG as with React. And it is also a good learning experience to work with a more complex use-case in Svelte to use the store and context concepts offered by Svelte.

Why using a radar for technology only?»

Good question! The radar visualization can be good for other stuff as well. The metaphor of a flight radar comes into mind. Planes appear and are being tracked on their way. But the radar visualization is more for tracking things in different sections, split up in the same orbits. Item might be added, migrated to another orbit or disappear again.

Most of the time, such a representation serves to find out what you or your team should focus on. You wouldn’t even need a technical tool, but could start at a blank paper canvas. Easiest step to make it digital would be, for example using a this Miro board ”What’s on Your Radar“.

Implementation details»

I won’t go into that deep into details or code samples, but can give you some high-level hints, how easy it is to build a radar visualization using Svelte and SVG.

TL;DR: or let me jump right to the Demo

Cutting in sub components»

      { "id": "02", "name": "ITEM 2", "description":  "", "sectionIndex": 0, "orbitIndex": 1, "attributeIndex": 1 },
      { "id": "03", "name": "ITEM 3", "description":  "", "sectionIndex": 0, "orbitIndex": 2, "attributeIndex": 2 },
      { "id": "04", "name": "ITEM 4", "description":  "", "sectionIndex": 0, "orbitIndex": 2, "attributeIndex": 2 },
      { "id": "05", "name": "ITEM 5", "description":  "", "sectionIndex": 1, "orbitIndex": 0, "attributeIndex": 0 },
      { "id": "06", "name": "ITEM 6", "description":  "", "sectionIndex": 3, "orbitIndex": 2, "attributeIndex": 0 },
      { "id": "07", "name": "ITEM 7", "description":  "", "sectionIndex": 3, "orbitIndex": 1, "attributeIndex": 1 },
      { "id": "08", "name": "ITEM 8", "description":  "", "sectionIndex": 5, "orbitIndex": 2, "attributeIndex": 1 }
    ]
  }

It was and still is a good exercise for clean code. I did cut things into components from the outside to the inside. The inner component actually put SVG pathes into the sites Markup.

Radar > n * Section > m * Oribit > k * Item with one of i * Attribute

Drawing Arcs»

A Section component represents a piece of the pie, but doesn’t directly draw SVG elements. It does so by using the Orbit component, which then is using the Arc component. The Arc component then draws a path. I fortunately already had a component for that, you find the source at the linked Demo.

The Orbit component also consists of Item components, which are rendered specific to their Attribute (new in, moved, no change).

Predictable random numbers»

The position of Items within an Orbit (or Arc) is random. But to make it predictable, I used Prando, a deterministic pseudo-random number generator. It can be used to create a series of random numbers that can later be re-created given the same seed.

So the position of Items looks random but does resample everytime, so you can find an Item where you saw it before.

I also use the triangular number formula to calculate places within an Orbit, because the inner length of an Arc is smaller than the outer length. So there’s more space the more you reach the outer side of the Orbit.

Store, Context and Tweens»

At first I worked with a store.js file. So I could access all the state from everywhere in the app, no need to pass props from component to sub component. And beside writable store variables, you can use the special store tweened, which makes animations easy. So whenever you set a new value to a tweened store, it interpolates the values automatically.

import { readable, writable } from 'svelte/store';
import { tweened } from 'svelte/motion';

export const radarRadius: writable(460);
export const orbitWeight: tweened(0.33, { duration: 400, easing: quadOut});

In a component it is easy like this. If you know Svelte, you probably know about the $ prefix in front of store variables.

<script>
  import { radarRadius, orbitWeight } from 'store.js';

  orbitWeight.set(1.0);
</script>

radar radius is: {$radarRadius}
orbit weight is: {$orbitWeight}

But this store was to global. As soon as I had two <TechRadar /> elements at a page, they both shared all the store values. So I went over to context and created kind of a context store.

import {
  setContext as setSvelteContext,
  getContext as getSvelteContext
} from 'svelte';

const CONTEXT_NAME = "radar";

export const setContext = () => {
  const context = {
    radarRadius: writable(460),
    orbitWeight: tweened(0.33, { duration: 400, easing: quadOut}),
  };
  setSvelteContext(CONTEXT_NAME, context);
  return context;
};

export const getContext = () => getSvelteContext(CONTEXT_NAME);

In a component I now can use the contextual store like this. Be careful, as you should use setContext() in your topmost component to build the context store, and getContext() in whatever sub component to access the same store variables.

<script>
  import { setContext } from './context.js';

  const {
    radarRadius,
    orbitWeight
  } = setContext();

  orbitWeight.set(1.0);
</script>
 
radar radius is: {$radarRadius}
orbit weight is: {$orbitWeight}

Custom Elements (Web Components)»

If I think of my Svelte based Tech Radar as a product, it would be nice, if everyone could create their own radar without compilation or dependencies, even without using node oder npm at all.

And this is possible, when compiling the Svelte component as a Web component or custom element. And because the data is changing not so much, we would not need to fetch it, but could instead put it as content of our custom element. And I could even support differen formats like JSON or CSV. Doesn’t that sound good?

There will be a new Svelte version 4 soonish (in May or June 2023) with better Custom element support. Maybe this will give this post another update. But until then, it was quite a hassle to get this running. But now you can use the whole TechRadar like in the following code snippet. Or you have a look at this Example page.

<script defer type="application/javascript"
  src="https://matthias.dittgen.name/blog/tech-radar/bundle.min.js"></script>
